Farmers’ knowledge and perception of risks associated with pesticides are core issues in adopting sustainable behavior related to pesticides. This study aimed to find out if Romanian farmers’ perceptions regarding the effects of conventional pesticides on pests, health, and the environment can predict farmers’ willingness to replace conventional pesticides with bio ones and to pay a higher price for the latter. This is the first investigation of Romanian farmers’ perceptions regarding pesticides, thus providing information useful both from the market and environmental protection perspectives. Binary logistic regression was performed to test the relationship between the perceived effect of pesticides, on the one side, and willingness to change conventional with bio-pesticides and willingness to pay for bio-pesticides, on the other side. It was found that the efficiency of conventional pesticides on combating pests and their effects on a farmer’s health can predict farmer willingness to replace conventional approaches with bio-pesticides. Conclusions disclose entry points for interventions aimed at improving communication and information strategies at the country level for raising awareness of the adverse effects of pesticide products, both at the food consumer and farmer levels.

The 2020 quarantine demonstrated that online food purchase has become one of the main protagonists of the pandemic. The present study valued the Internet as a mediator between producers and consumers with the power to create new demand for Romanian traditional food during the COVID-19 crisis. Authors aimed at carrying out an exploratory research about the online purchase of traditional foods (TFs). Within this context, the study, firstly, outlines the meaning of traditional foods in the Romanian consumers’ minds and, secondly, it identifies the variables that can predict the preference for the online purchase of TFs during the COVID-19 pandemic. An online survey was carried out to investigate the Romanian consumers’ perceptions (n = 223) of TFs and online purchase of TFs during the COVID-19 pandemic. Binary logistic regression tested the relationship between the preference for the online purchase of TFS (vs. in-store) and seven perceived characteristics of TFs. Results show that the preference for the online purchase of TFs during the COVID-19 pandemic can be predicted by five variables—“TFs taste”; “Effect of TFs consumption on health during the COVID-19 pandemic”; “Effect of online TFs purchase on health during the COVID-19 pandemic”; “How cheap/expensive is to buy TFS online during the COVID-19 pandemic”; and “Easiness to purchase TFS online during the COVID-19 pandemic”. It was concluded that TFs have to claim their place within this digitized landscape by finding the balance between old and new, between preferences for foods taste passed through generations and new life lifestyles at 5G speed.

Introduction: Glucagon-like peptide -1 (GLP-1) is released by intestinal cells to stimulate glucose-dependent insulin release from the pancreas. GLP-1 has been linked to ameliorating obesity and/or diabetic complications as well as controlling reproductive function. Liraglutide is a GLP-1 receptor agonist (GLP-1RA) with 97% homology with GLP-1. The main objective of this study was to investigate the ameliorative role of liraglutide in diabetic-induced reproductive dysfunction in male rats.Methods: Rats were randomly allocated into 3 groups; a control group, a diabetic group, and a liraglutide-treated diabetic group.Results: In the diabetic group, a significant increase in BMI, FBG, HbA1c, HOMA-IR, TC, TAG, LDL, IL6, TNFα, and MDA, as well as decreased serum insulin, HDL, GSH, total testosterone, LH, and FSH, were shown compared to the control group. Furthermore, A significant downregulation in relative hypothalamic gene expression of GLP-1R, PPAR-α, PGC-1α, kiss, kiss1R, leptin, leptin R, GnRH GLP-1R, testicular PGC-1α, PPARα, kiss1, kiss1R, STAR, CYP17A1, HSD17B3, CYP19A, CYP11A1, and Smad7, as well as upregulation in hypothalamic GnIH and testicular TGF- β and Smad2 expression, were noticed compared to the control group. Liraglutide treatment significantly improved such functional and structural reproductive disturbance in diabetic rats.Conclusion: GLP-1RAs ameliorated the deleterious effects of diabetes on reproductive function by targeting GLP-1/leptin/kiss1/GnRH, steroidogenesis, and TGF- β/Smad pathways.

Nano carriers have gained more attention for their possible medical and technological applications. Tailored nanomaterials can transport medications efficiently to targeted areas and allow for sustained medication discharge, reducing undesirable toxicities while boosting curative effectiveness. Nonetheless, transitioning nanomedicines from experimental to therapeutic applications has proven difficult, so different pharmaceutical incorporation approaches in nano scaffolds are discussed. Then numerous types of nanobiomaterials implemented as carriers and their manufacturing techniques are explored. This article is also supported by various applications of nanobiomaterials in the biomedical field.

The way people perceive climate change scientific evidence becomes relevant in motivating or demotivating their climate actions. Climate change is one of the most publicized topics globally, and media has become an important “validator” of science. Therefore, science has become more exposed to criticism. Even when most scientists, decision makers, and laypeople agree on the robust evidence of climate science, there is still room for disagreement. The main aim of this paper is to reveal how climate change knowledge generated by science is perceived by the laypeople and to observe a possible gap between them. The study answered two questions “What are the main contrasting climate change topics in the scientific literature?” and “What are Romanian and Belgian participants’ perceptions of these topics?”. A qualitative approach was chosen for data analysis, using Quirkos software. The present cross-country study showed commonalities and differences of views between the two groups of participants regarding six climate change topics. Divergent perceptions among Belgians and Romanians came out, for example, within the theme “The heroes, villains, and victims of climate change.” Thus, whereas Belgians considered all people, including themselves, responsible for climate change, Romanians blamed mostly others, such as big companies, governments, and consumers. Additionally, both groups stated that climate change existed, but contrary to Belgians, Romanians voiced that climate change was often used as an exaggerated and politicized topic. The analysis revealed that perceptions about climate change, its causes, and its impacts are social constructs with a high degree of variability between and within the two national groups. The study argued that the cleavages between scientific literature and people’s views were blind spots on which a participatory approach was needed to better cope with climate change challenges.

Introducing dental polymers has accelerated biotechnological research, advancing tissue engineering, biomaterials development, and drug delivery. Polymers have been utilized effectively in dentistry to build dentures and orthodontic equipment and are key components in the composition of numerous restorative materials. Furthermore, dental polymers have the potential to be employed for medication administration and tissue regeneration. To analyze the influence of polymer-based investigations on practical medical trials, it is required to evaluate the research undertaken in this sector. The present review aims to gather evidence on polymer applications in dental, oral, and maxillofacial reconstruction.
